Vibrafications is a tweak that allows you to set custom vibration patterns to different alerts. You can set a custom pattern for individual contacts in mail or sms, or you can set a default pattern for mail and sms in general, and you can define custom patterns for push notifications, or a default one for all push notifications. Patterns include things like vibrate three times for half a second each with a quarter second in between each vibration. No new icons are added to your home screen. Options can be configured in your Settings app. Need help jailbreaking your phone? These guides and tutorials will show you how to jailbreak your iPhone / iPad / iPod Touch.
